Application filed. October 29, 1907. Serial No. 399,660.

This invention relates to tires for automobiles, bicycles, buggies andother vehicles;

' and it has for its ob ect to The tube constitutin rovide a metallictirewhich shall belight,res' ient,non-sli ping and practically unctureproof; other 0 ects being to simpl' and improve the general constructionof the tire and a means for securing the same in position upon the rimof a vehicle wheel. I

- With theseand other ends in view which will readily appear as thenature of the invention is better understood, the same consists in i theimproved construction andnovel arrangement and combination of arts whichwill be hereinafter full describe and particularly pointed out in t eclaims.

- In the accom anying drawin' has been illusrated a simpFe andpreferreddorm of the invention; it being, however, understood that nolimitation is necessarily cise structural details therein exhibited, utthat changes, alterations and modifications within the scope of theinvention may be resorted to wh n desired. 4

In the dra g, Figure l is a side view of a wheel equipped with the imroved tire. Fi 2 is a transverse sectiona view, enlarged, taken throughthe rim of the wheel and the tire.

Corres onding parts in both figures are denoted by ike characters ofreference.

The improved tire consists of a tube 1 which may be made of an suitablemetal, saidtubular tire being ma e of any desired dimensions and ofannular shape to fit a wheel of the desired size. The manner or methodof manufacturing the tire does not constitute a part ofthe presentinvention. the tire is preferably made of ap roximate y circularcross-section but with. a attened inner side face 2 adapted to be seatedupon the corres ondingly flattened exterior surface3 of t ie rim 4 ofthe wheel to which it is applied. The wheel may be of any desiredconstruction and may be made of wood, metal or any other suitablematerial or combinations of materials, the rim 4 being provided with oneor more transmade to the reor recesses, one of which a Fig. 1 of thedrawings, for t e accommodation of alug 7 which is brazed or otherwisesecured upon the flat inner face 2 of the tire, for the purpose ofpreventing the latter from slipping or creeping when applied in position101 operation. *1

The rim 4 of the wheel is provided along on. of its side ed es with aflange 5 directly enaging one si e of the tubular tire 1 when the atteris placed in position upon the wheel rim; suitably secured upon the oposite side or edge of the rim is-an annular ange 6 consisting of a ringof metal or other suitable material; the latter being preferably held inposition, detachably, by means of bolts 7 threaded into the rim 4 andprovided with tightening nuts 8 and lock nuts 9.

Theltubular tire is provided upon its outer,- or hearing face, withjections 10, brazed or otherwise suitably secured thereu on and disposedat suitable in' tervals; saicf lugs serving by engagement with thesurface of the ground to prevent the wheel from slipping, thus greatlyincreasing the efiiciency of the tire.

From the foregoing description taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood. The construction of the improved tireis simple andinex ensive; being made of metal it is practicall y puncture proof; andthe metal employed in the manufacture of the tire being preferably of aresilient nature, it follows that the tire itself possesses aconsiderable degree of inherent resiliency which insures easy riding.The tire may bevory readily applied to the vehicle wheel where it isfirmly secured by means of the detachable ring or flange 6; and theconstruction is such to enable the parts to be very readily disassembledor reassembled as may be required. It is evident that the hollow ortubular metallic tire of the present invention may be filled with air,or other fluid, under pressure, thus enabling comparatively thin, lightand in expensivematerial to be used in the construction there of,without danger of collapsing; it is also deverse grooves pears at 4 intransverse lugs or pro-' sired to state that the anti-sli ping proiecaremovab side of the rim engaging the o dposite side of transverse ribsupon the flattened surface of the tire en aging'the'grooves in thexrim',and 15 is retaining flange atthesopnosite the tire and-engaging and hmlng said ribs seated in the grooves.

In testimony whereof I affix my signature 0 in presence of two W'ntnesses. 1 r
